  <div>
   <p>This section describes how to instantly recover a VM that has been backed up to the original location or a new location.</p>
   <div class="section">
    <h4 class="sectiontitle">Context</h4>
    <p>Backup copies, replication copies, and copies generated by live mount (copies that must have been unmounted from the VM) can be used for instant recovery. Data can be restored to the original or a new location.</p>
    <ul>
     <li>Restored to the original location
      <ul>
       <li>If you restore a VM to the original location, the system creates a VM in the path of the original VM (that is, the cluster or host to which the original VM belongs) and fully restores the backup data to the new VM.</li>
       <li>Data cannot be restored to the original location using a replication copy or copy generated by live mount.</li>
      </ul></li>
     <li>Restored to a new location<p>If you restore a VM to a new location, the system performs full restoration and restores the backup data to a specified new path. That is, the user specifies the host or cluster where the new VM is located and the corresponding storage pool.</p></li>
    </ul>
